Optional Features and Functions
a.
Route Diversity with Automatic Protection Switching (Alternate Entrance)
In order to provide this option DS-1 or DS-3 Service must be provided over end-to-end fiber
optic facilities and a separate entrance facility must be made available to the Telephone
Company.
Route Diversity with Automatic Protection Switching (Alternate Entrance) provides added
reliability to DS-1 or DS-3 Service. This feature provides a separate facility path for the
protection system between the serving central office and the Telephone Company Point of
Termination located in the same building as the customer designated premises.
This added protection is provided by ensuring that backup electronics and two physically
separate facility paths are used in the provisioning of the service. A primary (or working)
service path is established between the serving central office and the end user designated
premises. A secondary (or protect path) is provisioned between the end user designated
premises and the serving central office via the Telephone Company designated alternate
route. Should the working path or electronics fail, or the service performance becomes
impaired, i.e., the bit error rate degenerates to less than or equal to 10 to the minus 6, DS-1
or DS-3 Service will automatically switch to the service protect path in order to maintain a
near continuous flow of information between locations.
This option is only available where facilities permit.
